CC3000 interrupt latency

Customer is experiencing some "holes" in transmission when using the CC3000.

It seems like there is an interrupt latency every 200ms.

The delay occurs after sending HCI_CMND_SEND by SPI until an interrupt occurs on the CC3000.

SSID scan is disabled, is there other recommendations, that can be implemented to avoid this delay.

The delay is seen on the SPI communication:

  • HI Anders,

    Before I put too much thought into this, is there a compelling reason why customer is using CC3000 instead of CC3100? CC3000 is not recommended for new designs.
